Abstract: VORSETZER APPARATUS                      ABSTRACT OF THE DISCLOSURE Pedal actuator and connection assemblies?for electronic vorsetzer player piano units incorporating universal connection members between the electronic assemblies and foot pedals for con-verting a conventional piano to an electronic player piano are dis-closed,  The connection assemblies include a linkage having at the lower end a foot member, one for each foot pedal, which are adapt-ed to transmit actuating forces from the player piano unit down-wardly and on the rear portion of the pedal member pivoting the foot member in a second universal joint to cause an upward bias force on a lower pedal-engaging surface to thereby engage the lower side of the pedal therewith and thereby permit upward and downward movement of the foot without it slipping off the pedal.  A spring biases the linkage to just offset the conventional piano pedal spring and a dashpot having a fluid constricting passage dampens the solenoids' action, these elements coacting to avoid the tromp-ed down effect due to solenoid actuation. At the same time, since there is no positive securement of the connection assembly to the foot pedal, the vorsetzer may be easily and quickly positioned on the piano for converting a standard piano to an electronic player piano.

Abstract: Pharmaceutical Preparations Abstract of the Disclosure The invention concerns novel pharmaceutical preparations containing A) an extract of the mollusc Perna canaliculus, a mussel which is found on the shores of New Zealand, and B) a pharmaceutically active substance, especially medicaments having anti-phlogistic, anti-pyretic and/or analgetic action, which, when taken per se, may cause as a side effect irritation of the gastro-intestinal mucosae and possibly the formation of ulcers. The addition of a mollusc extract according to A) to the said medicaments has a gastro-protective action, in that the occurence of the said side effects is prevented or dimi-nished. The component A) is preferably used as a dry powder of the whole of the flesh of the mollusc or a dry powder obtained from the gonads thereof. In a typical preparation according to the invention an extract of the gonads is e.g. combined with acetyl-salicylic acid. The preparations may contain the 2 components in one and the same dosage unit form, e.g. a capsule or in 2 different ones, e.g. a cap-sule and a tablet.     The invention also includes a method for preventing, alleviating or treating gastro-intestinal irritation or ulcer formation by administering an effective amount of the mollusc extract as defined under A.

The armature bars are geometrically designed in such a manner that their volume is of an order of magnitude equalling that of the operating gaps.  In the starting position of the tongue, the armature bars are positioned in front of the operating gaps of the non-excited electromagnet.  Upon excitation of the electromagnet, the armature bars are pulled into the operating gaps, being accelerated in the process.

Abstract: METHOD OF AND APPARATUS FOR DETECTING               SPEECH IN A VOICE CHANNEL SIGNAL            Abstract of the Disclosure In a digital speech detector, a first detector produces an output signal if any sample of a voice channel signal has a magnitude exceeding a fixed threshold above noise levels.  A second detector produces a second threshold which is adaptively adjusted to noise levels on the channel by being set to a level above the current sample magnitude each time that this does not exceed the preceding sample's magnitude.  When the sample magnitude rises above the second threshold, and for each subsequent sample of successively increasing magnitude, the second detector produces an output signal.  A speech decision for the voice channel is reached if either detector produces its output signal.  The output signals of the first and second detectors are maintained for fixed and variable, respectively, hangover periods to maintain the speech decision during intersyllabic pauses in speech.  The samples are supplied to the speech detector by an offset remover and averaging circuit.                             - i -
